Detailed Description

The Dial widget is a valuator widget which is able to provide a cyclic value range when the DIAL_CYCLIC is passed, or a simple linear value range.

While being turned, the dial sends a SEL_CHANGED message to its target; at the end of the interaction, a SEL_COMMAND message is sent. The message data represents the current value, of type FXint. The options DIAL_VERTICAL and DIAL_HORIZONTAL control the orientation of the dial. An optional notch can be used to indicate the zero-position of the dial; display of the notch is controlled by the DIAL_HAS_NOTCH option.

Member Function Documentation

virtual FXint FX::FXDial::getDefaultWidth  )  [virtual]

Return default width.

Reimplemented from FX::FXFrame.

virtual FXint FX::FXDial::getDefaultHeight  )  [virtual]

Return default height.

Reimplemented from FX::FXFrame.

virtual bool FX::FXDial::canFocus  )  const [virtual]

Returns true because a dial can receive focus.

Reimplemented from FX::FXWindow.

void FX::FXDial::setValue FXint  value,
FXbool  notify = FALSE

Set the dial value.

FXint FX::FXDial::getValue  )  const [inline]

Return the dial value.

void FX::FXDial::setRange FXint  lo,
FXint  hi,
FXbool  notify = FALSE

Change the dial's range.

void FX::FXDial::getRange FXint lo,
FXint hi
const [inline]

Obtain the current range of the dial.

void FX::FXDial::setRevolutionIncrement FXint  i  ) 

Set the revolution increment, which is the amount of change in the position for revolution of the dial; the dial may go through multiple revolutions to go through its whole range; by default it takes one 360 degree turn of the dial to go from the lower to the upper range.

FXint FX::FXDial::getRevolutionIncrement  )  const [inline]

Get the current value of the revolution increment.

void FX::FXDial::setNotchSpacing FXint  spacing  ) 

Change the spacing for the small notches; this should be set in tenths of degrees in the range [1,3600], and the value should be a divisor of 3600, so as to make the notches come out evenly.

FXint FX::FXDial::getNotchSpacing  )  const [inline]

Get the current notch spacing.

void FX::FXDial::setNotchOffset FXint  offset  ) 

Change the notch offset, which is the position of the center notch; the value should be tenths of degrees in the range [-3600,3600].

FXint FX::FXDial::getNotchOffset  )  const [inline]

Get the current center notch offset.

void FX::FXDial::setDialStyle FXuint  opts  ) 

Changes the dial style.

FXuint FX::FXDial::getDialStyle  )  const

Get the current dial style.

void FX::FXDial::setNotchColor FXColor  clr  ) 

Change the center notch color.

FXColor FX::FXDial::getNotchColor  )  const [inline]

Get the current center notch color.

void FX::FXDial::setHelpText const FXString text  ) 

Set the help text to be displayed on the status line.

const FXString& FX::FXDial::getHelpText  )  const [inline]

Get the current help text.

void FX::FXDial::setTipText const FXString text  ) 

Set the tip text to be displayed in the tooltip.

const FXString& FX::FXDial::getTipText  )  const [inline]

Get the current tooltip text value.

virtual void FX::FXDial::save FXStream store  )  const [virtual]

Save to stream.

Reimplemented from FX::FXFrame.

virtual void FX::FXDial::load FXStream store  )  [virtual]

Load from stream.

Reimplemented from FX::FXFrame.
